Purpose: The main aim of the current study was to compare Spanish and Mozambican male and female secondary students, with regard to sexual behaviors and perceptions surrounding the acceptance of condom use. Method: The participants were 773 secondary students—412 from Spain and 361 from Mozambique, aged from 15 to 17 years old. Data collection was done using questionnaires. Analysis was carried out using multivariate methods. Results: Spanish adolescents took more precautions than Mozambican adolescents. Furthermore, Spanish adolescents perceived that the acceptance of condom use by their referents were higher than those reported by the Mozambican adolescents. Among Spanish youths, only the perceived acceptance of their current partner predicted condom use in their most recent sexual encounter. Discussion: Differences in the decision-making power of males and females and the type of partner might explain the differences observed in the preventive behavior of the students in both countries.

Youth internal assets and external resources are protective factors that can help youth avoid potentially harmful behaviors. This study investigates how the relationship between youth assets or resources and two sexual risk behaviors (ever had sex and birth control use) varied by gender. Data were collected through in-home interviews from parent—adolescent dyads, including 1,219 females and 1,116 males. Important differences exist between male and female adolescents. Females with the nonparental role models or the family communication resource were more likely to report never having had sexual intercourse than were females without the resources. Among males, the aspirations for the future and responsible choices assets were associated with never having had sexual intercourse. Males and females had two assets or resources in common that were protective of never having had sex: peer role models and use of time (religion). Considering which youth assets and resources are more likely to positively influence sexual behaviors of males and females may be important when planning prevention programs with youth.

This research was conducted to document behavioral patterns of the barking deer, Muntiacus muntjak (Zimmermann 1780) in captivity. All-occurrence and ad libitum sampling methods were used opportunistically to observe 15 barking deer at Dhaka Zoo in Bangladesh from April to November, 2011.A total of 54 behavioral patterns of the barking deer was recorded and described under 13 major heads. Of which, 41 behavioral patterns were similar for males and females and 13 were sex different. The highest observation was recorded for self-directed behaviors (21.55%) followed by consuming behaviors (20.84%), investigative behaviors (17.65%), scent markings and depositions (14.53%), relaxed states (13.98%), agonistic interactions (2.63%), foraging behaviors (2.31%), sexual behaviors (1.83%), submissive behaviors (1.66%), elimination (1.25%), movements (1.23%), vocalization (0.3%) and affinitive interactions (0.23%). The behavioral patterns were almost similar for male and female with several patterns showing variations. Females consumed food and took rest more frequently than males, who spent more time in foraging and movement. Males also showed higher frequency of sexual behaviors and less submissive behaviors. Environmental sniffing (n=792) was the most frequently encountered behavior and preaching (n=l) was the least. The present findings reveal that majority of the behaviors resemble that of other cervids, but nibbling and barking are unique to this species. Asiat. Soc.

Abstract Background In Mozambique, HIV infection disproportionately affects young adults, particularly women. Despite awareness and knowledge of HIV transmission, many university students have not received HIV testing and continue to engage in high-risk sexual behaviors, including inconsistent condom use. Further understanding of patterns of engagement with HIV prevention and testing is key to reducing HIV transmission in this at-risk population. Methods This study used a sequential mixed methods approach to examine patterns of engagement and perceptions of HIV prevention and testing services among higher education students in Mozambique. Survey data were collected from a representative sample of 501 students from Universidade Eduardo Mondlane (UEM) in Maputo, Mozambique to assess the primary outcomes of 1) HIV testing within the last 12 months; and 2) condom use during last sexual encounter. We employed univariate and multivariate regression models. The survey was followed by qualitative interviews with 70 survey participants which were analyzed using an inductive, content-focused analysis to further explain and contextualize survey findings. Results Over 85% of students reported to be sexually active, among these 74% reported condom use during their last sexual encounter, and 64.2% reported an HIV test within the past 12 months. Females were more likely to have had HIV testing in the past 12 months in comparison to their male peers (aOR 1.82, 95% CI 1.11, 2.99), but were half as likely to have used a condom with their last sexual encounter (aOR 0.52, 95% CI 0.33, 0.83), when controlling for other factors. Qualitative data suggests that these discrepancies may be explained by differential perceptions in risk and trust/mistrust, with women being more concerned about infidelity by their male partner(s) and assuming more responsibility for knowing their own serostatus. Women were also subject to negative stereotypes for possessing condoms in comparison to men, which could explain lower propensity for use. Conclusion Given gendered differences in uptake of condom use and HIV testing, and perceived HIV risk, interventions tailored specifically to male and female students may impact engagement with HIV prevention and testing and empower informed choices about sexual behaviors.

Abstract Background The risky behaviors of youngsters or youths may further be worsened by the logic that university students are too many in number, lack facilities for sexual and reproductive health services and live away from their parents and free from parental control. To tackle the issue, evidence based intervention like improved access for youth’s friendly reproductive health services is crucial. In Ethiopia, despite the fact that much has been said about sexual and related issues of higher institution students, the assessment of the problem is not widely covered and search for solutions is mostly after the problem become deep-rooted. So, the purpose of this study was to assess the level of risky sexual behaviors among Wolkite University (one of the public higher institute) students. Methods A facility based cross-sectional study was employed using Cluster sampling to identify 1,123 students’ from each college, departments & sections of the colleges in the University, list of clusters (groups) was established with area of study and year of study. To select these clusters, list of cumulative frequencies of number of students was calculated. The total sample size was divided proportionately to the selected clusters and to both sexes (male and female). Accordingly, males and females were selected based on percentages calculated. Finally, a systematic sampling method was applied to select males and females from the cluster selected for the study after dividing the cluster in to male and female groups. Result In this emerging university ever use of substance reportedly was somewhat higher than a quarter, 28.7% (322) from a total of 1123 students. Among students reported ever use of substances, alcohol consumption was the predominant one, 157(14.0%), followed by khat, 57 (5.1%). Conclusion and recommendation The institute needs substantial progress in availing youth friendly reproductive health services as huge number of the youngsters, 225(20%) had risky sexual behavior and currently 7(1.5%) were HIV positive. Moreover, services for youths should be friendly and available with skillful professionals. This can be realized through the effort of tremendous stakeholders in the compound and elsewhere in the country like ministry of education/health or non-governmental organizations.

Neuroendocrine mechanisms underlying complementary behaviors like male-typical mounting and female-typical receptivity are most often studied independently in males and females, respectively. Cnemidophorus uniparens is a unisexual lizard species consisting only of females that alternately express male- and female-like pseudosexual behavior across the ovarian cycle. Intact, postovulatory (PostOv), and ovariectomized (OVX), androgen-implanted animals [OVX plus testosterone (T)] exhibit male-like mounting, but not receptivity, whereas intact, preovulatory (PreOv), and OVX lizards injected with estradiol [OVX plus estrogen (E)] express receptivity, but not mounting. We tested whether the serotonergic system in the preoptic area (POA) and ventromedial nucleus of the hypothalamus (VMN) gates the reciprocal inhibition characterizing this alternating expression of mounting and receptivity. Serotonergic signaling at the POA appears to be key to gating male-like behavior. Postovulatory and OVX plus T animals have lower intracellular serotonin (5-HT) levels, and greater abundance of inhibitory 5-HT1A receptor mRNA in the POA compared with both PreOv and OVX plus E lizards. Moreover, injecting 5-HT into the POA of OVX plus T animals suppresses mounting, whereas injection into VMN of OVX plus E lizards suppresses receptivity. Although 5-HT levels in the VMN do not differ across the ovarian cycle or between hormonally manipulated animals, PreOv and OVX plus E lizards have a lower abundance of 5-HT2A mRNA in the VMN. Stimulating 5-HT1A receptors using systemic drug administration inhibits mounting, whereas activating 5-HT2A receptors facilitates receptivity. This study illuminates how male- and female-typical sexual behaviors share common neural circuits, and that 5-HT regulates these naturally complementary, and mutually exclusive, behaviors.

ABSTRACT The effects of various doses of testosterone propionate (TP) upon the release of luteinizing hormone (LH or ICSH) from the hypophysis of a gonadectomized male or female rat were compared. Prostate weight in hypophysectomized male parabiotic partners was used to evaluate the quantity of circulating LH. Hypophyseal LH was measured by the ovarian ascorbic acid depletion method. Males castrated when 45 days old secreted significantly more LH and had three times the amount of pituitary LH as ovariectomized females. Administration of 25 μg TP daily reduced the amount of LH in the plasma, and increased the amount in the pituitary gland, in both sexes. Treatment with 50 μg caused a further reduction in plasma LH in males, but not in females, while pituitary levels in both were equal to that of their respective controls. LH fell to the same low level in partners of males or females receiving 100 μg TP. When gonadectomized at 39 days, males and females had the same amount of plasma LH, but males had more stored hormone. Pituitary levels were unchanged from controls following treatment with 12.5, 25 or 50 μg TP daily, but plasma values dropped an equal amount in both sexes with the latter two doses. Androgenized males or females, gonadectomized when 39 days old, were very sensitive to the effects of TP and plasma LH was significantly reduced with 12.5 μg daily. Pituitary LH in androgenized males was higher than that of normal males but was reduced to normal by small amounts of TP. The amount of stored LH in androgenized females was not different from that of normal females and it was unchanged by any dose of TP tested. Results are consistent with the conclusion that the male hypothalamic-hypophyseal axis is at least as sensitive as the female axis to the negative feedback effects of TP. Androgenization increases the sensitivity to TP in both males and females.

Background. African American adolescents and young adults have an increased likelihood of engaging in risky sexual behaviors. With rising rates of sexually transmitted infections among this population, deeper consideration is now being focused on using social media to engage, educate, and improve sexual behavior in this group. Purpose. To determine why social media is useful and how it may affect the attitude, norms, and perceived behavioral control on condom use among young African American males (YAAMs) ages 18 to 21. Method. Group-depth interviews ( n = 41, mean age = 19, SD = 1.2) were conducted in metro Detroit to understand and describe the who, what, where, why, and how regarding social media use and preference among YAAMs) ages 18 to 21, and their condom use behaviors. Results. The most popular reasons for using social media were for educational purposes, entertainment, browsing the site, self-expression, seeking out or maintaining relationships with friends and family, and social justice. YouTube was stated as the easiest site to promote condom use education. YAAMs would seek out condom use education on social media sites if someone respected in the community or someone famous promoted condom use messages on the sites or if it was used to show where condoms were available for free or for purchase. Conclusion. Understanding how YAAMs use social media may help researchers design better questions to address disparities within this population. More important, it can help health care providers, families, and the community promote healthy behaviors and lifestyle changes among YAAMs.

Spinal muscular atrophy (SMA) is a genetically heterogeneous group of rare neuromuscular diseases and was until recently the most common genetic cause of death in children. The effects of 2-month nusinersen therapy on urine, serum, and liquor 1H-NMR metabolomes in SMA males and females were not explored yet, especially not in comparison to the urine 1H-NMR metabolomes of matching male and female cohorts. In this prospective, single-centered study, urine, serum, and liquor samples were collected from 25 male and female pediatric patients with SMA before and after 2 months of nusinersen therapy and urine samples from a matching healthy cohort (n = 125). Nusinersen intrathecal application was the first therapy for the treatment of SMA by the Food and Drug Administration (FDA) and the European Medicines Agency (EMA). Metabolomes were analyzed using targeted metabolomics utilizing 600 MHz 1H-NMR, parametric and nonparametric multivariate statistical analyses, machine learning, and modeling. Medical assessment before and after nusinersen therapy showed significant improvements of movement, posture, and strength according to various medical tests. No significant differences were found in metabolomes before and after nusinersen therapy in urine, serum, and liquor samples using an ensemble of statistical and machine learning approaches. In comparison to a healthy cohort, 1H-NMR metabolomes of SMA patients contained a reduced number and concentration of urine metabolites and differed significantly between males and females as well. Significantly larger data scatter was observed for SMA patients in comparison to matched healthy controls. Machine learning confirmed urinary creatinine as the most significant, distinguishing SMA patients from the healthy cohort. The positive effects of nusinersen therapy clearly preceded or took place devoid of significant rearrangements in the 1H-NMR metabolomic makeup of serum, urine, and liquor. Urine creatinine was successful at distinguishing SMA patients from the matched healthy cohort, which is a simple systemic novelty linking creatinine and SMA to the physiology of inactivity and diabetes, and it facilitates the monitoring of SMA disease in pediatric patients through non-invasive urine collection.

Background and purposeThe therapeutic potential of different stem cells for ischaemic stroke treatment is intriguing and somewhat controversial. Recent results from our laboratory have demonstrated the potential benefits of human umbilical cord blood-derived mesenchymal stem cells (MSC) in a rodent stroke model. We hypothesised that MSC treatment would effectively promote the recovery of sensory and motor function in both males and females, despite any apparent sex differences in post stroke brain injury.MethodsTransient focal cerebral ischaemia was induced in adult Sprague-Dawley rats by occlusion of the middle cerebral artery. Following the procedure, male and female rats of the untreated group were euthanised 1 day after reperfusion and their brains were used to estimate the resulting infarct volume and tissue swelling. Additional groups of stroke-induced male and female rats were treated with MSC or vehicle and were subsequently subjected to a battery of standard neurological/neurobehavioral tests (Modified Neurological Severity Score assessment, adhesive tape removal, beam walk and rotarod). The tests were administered at regular intervals (at days 1, 3, 5, 7 and 14) after reperfusion to determine the time course of neurological and functional recovery after stroke.ResultsThe infarct volume and extent of swelling of the ischaemic brain were similar in males and females. Despite similar pathological stroke lesions, the clinical manifestations of stroke were more pronounced in males than females, as indicated by the neurological scores and other tests. MSC treatment significantly improved the recovery of sensory and motor function in both sexes, and it demonstrated efficacy in both moderate stroke (females) and severe stroke (males).ConclusionsDespite sex differences in the severity of post stroke outcomes, MSC treatment promoted the recovery of sensory and motor function in male and female rats, suggesting that it may be a promising treatment for stroke.
